In the event of a primary site failure due to unplanned environmental catastrophes or any system failures, the external NFS/CIFS clients that are using the file system(s) served by the NAS-server active on the primary site experience a Data Unavailability (DU) situation. In such scenarios, the Administrator can run the replication failover option to quickly mitigate the DU scenario.
NOTE: This operation is performed on the destination site in case of a disaster (source site unavailable). Start needs to be performed after the original source is brought up.
This operation will reverse the direction of the replication session and makes the nas server in production mode on the original destination.
Follow the below steps to perform unplanned failover of the replication session:
Select
Data Protection.
Select
File Protection.
Click
REPLICATION tab.
Click
REPLICATION SESSION tab.
Select the checkbox against the name of the replication session you want to perform an unplanned failover.
Click
More Actions.
Click
Unplanned Failover. The Unplanned Failover Replication Session wizard opens.
Click
Run In The Background to proceed with the Unplanned Failover.
Go to the job list in the UI and click on view all jobs.
Click on the hyperlink beside the planned failover without auto-start job to track the status.
This operation now performs an Unplanned Failover.
